Hmm. This is interesting. I wouldn’t do it if it meant 6 hours committed in the park(s) (meaning if it’s still one FP per hour). That would hog up too much of my day and be a waste of our time on filler stuff we’re not super interested in waiting for the next window to open. I’d much rather spend my down time at the pool or lounge. Allowing me to overlap the 6 FPs so I could get in mores rides and still have my down time, I’d do it in a heartbeat.
If it’s multi park, that’s appealing but again, it’s too much a chunk of the day tied up. We’re sleep in, hit the parks by 11am, spend 3-4 hours, pool, lounge, dinner/perhaps another park and more lounge people. With that pace, I can’t see carving out 3 more hours and not enjoy the resort amenities I’m also paying for.
